Made in the USA with a 1-year warranty, it includes everything needed for easy setup and ongoing water quality testing. ## Description ControlOMatic MegaChlor-CD Saltwater Chlorine Generator with Built-In Chlorine Detection MegaChlor-CD is the only saltwater chlorine generator for swim spas and above ground pools with chlorine detection built into the electrode. In other words, it knows when to turn on, right when your water needs more chlorine. When it turns off, it will be off until it detects that it needs more chlorine, preventing overchlorination. MegaChlor-CD eliminates the guesswork. MegaChlor-CD features two components: an easy-to-use control box that can be mounted to your pool/spa's skirt and a drape-over electrode. Since it drapes straight into the main body of water, you don't need to modify your swim spa or above ground pool. Add 25 pounds of salt per 1000 gallons of water, and then place the electrode in the tub. From there, just plug the power supply into a wall outlet, and your MegaChlor-CD is ready to generate chlorine!

Review: Good unit. - FAST SERVICE.Nice product. Review: Works Like A Charm - Only Wish I Knew About This Years Ago! - Update 8/14: works amazingly well. After being away over a month the hot tub levels remained perfect and water clear. Photos added. Original: I only wish I knew about this years ago. I converted my pool to salt water years ago and love it. One of the best features is that it only cycles on (smarterspa model) when the sanitizer level drops below a certain threshold. This is great for us because our hot tub is covered, and used irregularly in terms of frequency and number of occupants, so manning the chemicals has always been a challenge. Day 1, I installed it, it ran a cycle at level 3 (default) with only 2/3 of the weight of salt recommended in the manual as per the youtube video recommendation. The sanitizer level rose to pool levels but needed to be higher for a spa, so I increased to level 4 and later that day it cycled again. Day 2, spa levels are all perfect with sanitizer levels at the desired level for a spa. This was SO EASY! Now, my hope is that the unit has longevity. From my pool salt chlorine generator experience, my expectation is at least 3 years, hoping for 5. I hope to come back here to update my review if my expectations are not met, especially if it dies within a year. My only negative is that the video on youtube by the manufacturer talks about being able to install this inside the housing attached to the spa electrical (advanced install) but I did not see any instructions for this. I will try to reach out but I would have liked to see instructions and/or a video online demonstrating this. We are very excited about this, and although the price is not as low as I would like, it is still in an acceptable range for the convenience and chemical cost savings if it lasts at least 3 years, in my opinion. It is priceless in terms of the improvement to the water quality for my skin, however, and as such as totally worth it. ## Features - GENERATES CHLORINE FROM SALT – The MegaChlor-CD spa and above ground pool chlorinator automatically turns on if chlorine levels are too low and produces chlorine using a small amount of ordinary salt (sodium chloride) dissolved in water. MegaChlor-CD is the only salt chlorine generator on the market that powers on automatically, keeping your water perfectly chlorinated at all times. - GENTLE ON EYES AND SKIN – The electrolysis process produces chlorine from salt, which naturally softens water for above ground pools and swim spas up to 17,000 gallons. The soft, gentle feel makes the MegaChlor-CD a better choice for those with sensitive skin. - SIMPLIFIES POOL MAINTENANCE – The MegaChlor-CD chlorinator is the only saltwater chlorine generator for residential spas and above ground swimming pools with chlorine detection built into the electrode. The self-cleaning reverse polarity system reduces time spent worrying about maintenance, giving you more time to relax and enjoy the clean water. - EASY TO INSTALL AND USE – Using its built-in chlorine detection system, the MegaChlor-CD will generate only what it needs, when it needs it. This plug-and-play system does not require any plumbing or mechanical alterations. Instead, the electrode drops straight into the main body of water and automatically chlorinates from there. Megachlor-CD offers a simple solution for converting spa systems to saltwater and is compatible with manufacturer warranties due to its lower salt usage. - MADE IN THE USA – All ControlOMatic products are made in the USA and come with a 1-year warranty. The package includes a MegaChlor-CD Control Box, MegaChlor-CD Electrode, 12 VDC Power Supply with 110-240 VAC Input, test strips (salt, free chlorine, pH, alkalinity, hardness), a card with QR code for Warranty activation and User Manual. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01ITWC8FA | | Brand | ControlOMatic | | Brand Name | ControlOMatic | | Customer Reviews | 4.0 out of 5 stars 261 Reviews | | Item Form | Granular | | Item Weight | 110 Grams | | Item form | Granular | | Item weight | 110 Grams | | Manufacturer | ControlOMatic | | Manufacturer Part Number | megachlor-cd | | Model Number | megachlor-cd | | Number of Items | 1 | | Product Benefits | Maintains Clean Sanitized Water | | Product benefits | Maintains Clean Sanitized Water | | UPC | 699466711218 | | Unit Count | 1 Count | ## Product Details - **Brand:** ControlOMatic - **Item weight:** 110 Grams - **Item form:** Granular - **Product benefits:** Maintains Clean Sanitized Water - **UPC:** 699466711218 ## Images ![MegaChlor-CD Saltwater Chlorine Generator with Auto Chlorine Monitoring, Automatically Activates as Needed, for Swim Spas and above Ground Pools Up to 17,000 Gallons - Image 1](https://m.media-amazon.com/images/I/61P1la5xA+L.jpg) ![MegaChlor-CD Saltwater Chlorine Generator with Auto Chlorine Monitoring, Automatically Activates as Needed, for Swim Spas and above Ground Pools Up to 17,000 Gallons - Image 2](https://m.media-amazon.com/images/I/81pnGigla6L.jpg) ![MegaChlor-CD Saltwater Chlorine Generator with Auto Chlorine Monitoring, Automatically Activates as Needed, for Swim Spas and above Ground Pools Up to 17,000 Gallons - Image 3](https://m.media-amazon.com/images/I/91COPAkOF9L.jpg) ![MegaChlor-CD Saltwater Chlorine Generator with Auto Chlorine Monitoring, Automatically Activates as Needed, for Swim Spas and above Ground Pools Up to 17,000 Gallons - Image 4](https://m.media-amazon.com/images/I/812RSnI6iSL.jpg) ![MegaChlor-CD Saltwater Chlorine Generator with Auto Chlorine Monitoring, Automatically Activates as Needed, for Swim Spas and above Ground Pools Up to 17,000 Gallons - Image 5](https://m.media-amazon.com/images/I/41TG5Z6hv3L.jpg) ## Questions & Answers **Q: Does the chlorine sensor shut unit off at a predetermined level?** A: The MegaChlor will produce chlorine for a period of time and then go into an off-cycle (standby mode) for 3 hours and then repeat. The length of time for the on part of the cycle is determined from the power level setting and is 30 minutes for power level 1, 1 hour for power level 2, and an additional hour per power level. On level 3 it will be on for 2 hours. For more information, you can download its user manual at [controlomatic. com/wp-content/uploads/2020/12/MegaChlor-Manual-for-Website-2020. pdf] **Q: What does the chlorine detector do if it doesn’t shut the unit off when level is reached?** A: It shuts the unit off, when it reaches the output level. It allows you to control the chlorine level and not overchlorinate. Alan **Q: what are the actual dimensions of the control unit?** A: The controller dimensions are approximately: 7" in width x 4.5" in height x 1.5" in depth. I hope that this is helpful. Best regards, Adam Lawrence customer service todayspoolandspa **Q: how much DC voltage is going through The cell?** A: 5 volts, is what I have been told. I hope that this is helpful.

Seems after you drain the water refill check the water then come back in two days to a sour smell. Our friends have a salt water pool with attached hot tub and their water always seem to be nice with no harsh smell. Ordered this after talking in depth to ControlOMatic and how this should help us out. Drained hot tub, refilled, We are lucky as our water is spot on for PH, alkalinity and hardness out of the tap. Added the amount of salt calculated by the gallons of water, took all of about 2 minutes to install the Smarter Spa, most of that was getting it out of the box. 3 screws, 2 to hold the box and one to hold the cord. Dropped it in and it read salt overload. drained some water added fresh, still salt overload. Drained about half the tub, added water back dropped the module back in and it registered Salt High which is fine per the directions. Lesson learned, add about half the salt and then test. This unit reads the salt level instantly so no need to wait. It produces the right amount of chlorine and turns itself off and when it needs more it turns itself back on. Only 5.5 DC volts. I could not be more pleased with it and a 40lb bag of salt from Walmart is less than $7.00 I only needed about 4 cups so I am set for the next 5 years for salt. So no more aroma therapy to cover up the yuk smell for us. ## Frequently Bought Together - ControlOMatic MegaChlor-CD Saltwater Chlorine Generator with Auto Chlorine Monitoring, Automatically Activates as Needed, for Swim Spas and above Ground Pools Up to 17,000 Gallons - Pool Salt Tester & PH Meter, Hofun Digital Salinity Meter and PH Tester for Aquarium and Pool Saltwater Water, 5 in 1 Salinity PH Temp EC and TDS Meter, Aquarium Swimming Pool Hot Tub, High Accuracy --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/735828649-megachlor-cd-saltwater-chlorine-generator-with-auto-chlorine-monitoring-automatically](https://www.desertcart.hr/products/735828649-megachlor-cd-saltwater-chlorine-generator-with-auto-chlorine-monitoring-automatically) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-29*
